Abstract EN

A dynamic model of a two-axis rate gyro-stabilized platform-based seeker with cross-coupling, mass imbalance, and disturbance torque is developed on the basis of the working principle of seeker two-loop steady tracking theory; coordinate transformations are used to analyze the effects of seeker servo control mode on missile guidance and control systems.

Frequency domain is used to identify the servo motor transfer function.

Furthermore, a block diagram of the two-gimbal-coupled system is developed, and the coupling characteristics of gimbal angle are analyzed with different missile body inputs.

Simulation results show that the analysis conforms with the actual movement rule of seeker gimbal and optical axis, and cross-coupling exists between the two gimbals.

The lag compensation network can increase the open loop gain and increase the capacity for disturbance rate rejection.

Simulations validate the theory and technology support for developing the seeker servo control model in engineering.
